Hi Rafael

What kind of help do you need?
I'm using Shane's bootloader, slightly modified to suite my needs as far
as the CONFIG bits are concerned. I wrote my own downloader program for
OS/2, and the combination works OK.
With the type 'A'-PICs (16F87xA) and the special bootloader for these,
the hex-file must have a multiple of 4 code-words (insert NOPs if
needed). I had similar problems as you report when I wasn't aware of
this requirement.

Regards, Rob.
